lMPROVEMENT IN FIRE-PLACES.

Specification forming part of Letters Patent No. 40,989, dated December22, 1863.

To all whom it may concern:

Be it known that we, A. 0. BACON and JOHN G. J ENNINGS,.Of the city ofCleveland, in the county of Ouyahoga and State of Ohio, have inventednew and useful Improvementsin Fire- Places and we do hereby declare thatthe following is a full and complete description of the construction andoperation of the same, reference being had to the accompanying drawings,making part of this specification, in which- Figure 1 is a front view.Fig. 2 is a vertical section. Fig. 3 is a transverse vertical section inthe direction of the lines a" :10 in Fig. 1, and Fig. A is a view of theblower.

Our invention relates to an improved register fireplace, which, by acombination of airchambers, forms an open grate of increased radiatingpower, either for a chimney or stove, and that will also furnish thehot-air draft of a register. The chamber A is made to extend around theback and sides of an ordinary or open grate, into which chamber air isadmitted from below. From the top of the fireback the arched chamber 13,connecting with the chamber A, is made to project over the tire, which,by its form and position, concentrates the heat beneath, thus increasingits radiation and the temperature of the air within. Along and beneaththe lower margin of this arch are apertures c c c for the egress of airfrom the chamber into the flame. The front or blower, Fig. 4, isprovidedin itsupper section with small perforations, (seen at a,) and which, incombination with the apertures c and front blower, D, serve to cause amore complete combustion of the smoke and gas, and to intensitytheheatinthe chamber above. From the sides of the grate athird air-chamber, E,connected with the chambers A and B, extends over the arch of thesmoke-flue F, from which heated air is conducted through the reg ster Ginto the room, or by closing this register the hot-air may be conveyedthrough the hotair flue H upon the back side of the chamber E, andthence into an adjoining room or into an upper room, as may be desired.The blower D fits closely to the hearth and jambs, and is provided atthe bottom with a sliding damper, D, which is to be opened when a strongdraft is required, but when the coal or other fuel becomes properlyignited the damper D may be closed. The perforations a in the uppersection of the blower D are sufficiently small (from atenth to atwentieth of an inch in diameter) to prevent the ingoing current of airfrom deflecting the rising current of gas from the burning fuel, butstill large enough to admit a sufficient quantity of air to cause, inconjunction with that which enters through the apertures cc 0, acomplete combustion of the gas. Thus, by the relative positions of theair-chambers A, B, and E, and the agency of the apertures c andperforations a in the blower D, the greatest radiating power of thegrate is obtained, while the air, in passing successively through thechambers named, becomes charged with the greatest available heatpossible before it issues from the register G or is conveyed to anotherroom by the hot-air flue H.

This fire-place may be used as a stove by attaching a suitablesmoke'pipe to the opening F, or it may be set as an ordinary firegrate.

What we claim as our improvement, and desire to secure by LettersPatent, is-

1. The combination of the several air-chambers A B E, forming an opengrate of increased radiating power for a chimney or stove, that willalso furnish the heated-air draft of a rcgister-viz., the chambers A,eX-' tending around the back to the sides of the grate, and into whichair is admitted from below, the arched chamber 13, projecting from thesummit of the chamber A, with which it is connected over the fire, withmore or less inclination, as the nature of the draft may require, andthe chamber E, meeting the Ollttllb bers A and B in the sides of thegrate and extending over the arch of the smoke-flue, all combined in themanner and for the purposes substantially as described.

2. The apertures c, in their application to the herein-describedgrate,in combination with the movable perforated front or blower D, whenconstructed as described, and operating as specified.
